SIG 228 Stainless Mags?

[plnkr1234]

Anyone know if SIG 228 magazines were ever produced in stainless? Saw some at a gunshow that appeared to be, but could also have been hard chromed.

thanks

I have two of these. They came with Sigs that were electroless nickel plated. They are HARD to find and would probably fetch close to $100 for one. I am unsure wether they are stainless or nickeled, bt they are very different from Sigs black mags.
